The calendar below, created by Dr. Peter Yuichi Clark, is an excellent way to keep on top of religious high holy days and festivals as they go by. It is especially useful for those in interfaith vocations who need this information on a day-to-day basis.

TIO is cooperating with another “working” religious calendar project being led by Read the Spirit. It extends what we usually mean by religious calendar to include important civic holidays. It identifies major religious holidays more than a year in advance. Most important, it features stories about what these many religious festival events are all about – what they mean, the important stories, the food associated, and how particular events are celebrated. Your own stories of religious holidays, whatever your tradition, are welcomed at the site. Check it out!
